As the typhoon raged outside, the group of friends huddled in the grand living room of Rokkenjima. Mobin, the wealthy owner of the island, offered to play bartender while Ali, Amin, Arian, and Anahita relaxed on the couches. Saber sat apart in a corner, still nursing a grudge against Mobin. Suddenly, a sealed letter appeared on the dinner table. They each looked at each other, frightened and wondering where it came from. "It's from a witch called Beatrice," Ali read aloud. "She says she'll kill us all before the typhoon passes." The group laughed nervously, but their mirth quickly turned to despair when the deaths began. Arian was found in a locked room with no foreseeable way for the murderer to slip in. MohammadMehdi was found hanging from a chandelier, in a room that nobody else had been in. MohammadHossein was found impaled on a tiger trap, and then Amir was discovered, with his body found with knives three inches deep inside each eye. Saber then accused Mobin of being the culprit, and blamed him for all the deaths. In his defense, Mobin said that there was no way he could have done it, as the sealed letter appeared on the table while they were all in the room. He also said that there was no way he could have committed some of the deaths. The group soon realized that they were trapped on the island, with no way to call for help. They became prisoners of the typhoon and the perpetrator. Each person started to suspect the other, knowing that one of them was the enigmatic witch and their time was running out. The mystery was revealed shortly before Seagulls cried the last time. All the remaining members of the group had died - even though they didn't know who the murderer was, they all knew the culprit had to be one of them. As an ominous silence swept over the island, the death toll went from one to ten. And when the seagulls cried, none were left alive. The mystery of Rokkenjima would forever remain unsolved.
